I have seen a couple posts about this mask. My wife and I currently own Oceanreef Neptune Space FFM for OC. I am curious if anyone has any input on using communications with the Drager. How effective is it with a mouth piece crammed in your mouth. Is it still possible to understand someone using this? Also maybe this is a dumb question but why is the mouth piece needed? I read the article here:

And it states that if used with the dolphin w/o the mouth piece it would blow the mask off your head. Is this the same with all Rebreather combined with this mask?
Also how are the "P" connectors on it constructed. Would I be able to use the GSM DC transceiver unit I use with the Space FFM? It is compatible with any FFM that uses a standard DIN female connection.
Thanks for any advice.
